gnutls_pkcs12_mac_info - API function

gnutls_pkcs12_t pkcs12 A pkcs12 type unsigned int * mac the MAC algorithm used as gnutls_mac_algorithm_t void * salt the salt used for string to key (if non-NULL then salt_size initially holds its size) unsigned int * salt_size string to key salt size unsigned int * iter_count string to key iteration count char ** oid if non-NULL it will contain an allocated null-terminated variable with the OID

This function will provide information on the MAC algorithm used in a PKCS 12 structure. If the structure algorithms are unknown the code GNUTLS_E_UNKNOWN_HASH_ALGORITHM will be returned, and only oid , will be set. That is, oid will be set on structures with a MAC whether supported or not. It must be deinitialized using gnutls_free(). The other variables are only set on supported structures.

GNUTLS_E_INVALID_REQUEST if the provided structure doesn't contain a MAC, GNUTLS_E_UNKNOWN_HASH_ALGORITHM if the structure's MAC isn't supported, or another negative error code in case of a failure. Zero on success.
